Lean muscle mass refers to the amount of muscle on your body minus the fat. It's the portion of muscle that is non-fatty, functional, and metabolically active. Having more lean muscle:

  • Speeds up your metabolism since muscle burns more calories than fat
  • Helps you burn more calories even at rest
  • Gives you strength, endurance, and energy
  • Supports functional movement and prevents injury
  • Contributes to an athletic, toned appearance
  • Promotes healthy aging as we tend to lose muscle as we get older
Some key differences between lean mass and fat mass: Lean Mass
  • Mostly water, protein, glycogen
  • Metabolically active
  • Burns calories
  • Functional - allows movement
  • Shape changes with training
Fat Mass
  • Mostly adipose tissue
  • Metabolically inactive
  • Stores calories
  • Less functional, slows movement
  • Shape less responsive to training
You can build lean muscle through:
  • Strength training with weights/resistance
  • Getting enough protein in your diet
  • Allowing proper recovery between workouts
  • High intensity interval training (HIIT)
  • Compound exercises working multiple joints/muscle groups
The amount of lean mass that is ideal depends on factors like:
  • Sex - men tend to have more muscle than women
  • Genetics and body type
  • Goals - athletic performance vs aesthetics
  • Age - muscle tends to decrease with age
Building lean muscle takes time and consistency. But the payoff for your metabolism, mobility, strength, and health is immense. Evaluating your current lifestyle and tailoring a sustainable exercise and nutrition program is key. I aimed to provide an informative overview of lean muscle mass, highlighting key properties, differences from fat, and tips to build it. For more information, please contact Thrive Hormone Therapy.
